What kinds of diseases and disorders exist?
One of the most common disorders that have been found to correlate with the age of the mother is trisomy 21. Another name for trisomy 21 is Down syndrome. The name "trisomy" means that chromosome 21 exists three times instead of just two. This results in various disorders, among which are heart defects and mental handicaps.
There also exist other kinds of chromosomal abnormalities such as the Turner syndrome. Some are more severe; others impose only few restrictions on life.
